Currently I don't care about milk production so am thinking about getting a couple wethers. I've got lots of browse they can eat as well.I can ask, most goat people I know have Nigerian Dwarf also. I think the all are capable of it. IT's a matter of your management and how many you want to shelter. The people I bought my first two from got them to clear off acreage. I care about milk production so they get fed timothy and/or alfalfa, if I didn't care about the milk and let them live off browse they could/would clear areas. Keep in mind goats are browsers, like deer, eat a little some place and move on.
